1 s claims. (ci. 56-470) This invention relates broadly to grain binders and more particularly tov grain. bindersk of the type embodying laterally shifting platforms and packersgand an object -of the invention is to provide in conjunction with the platform improved m'eansior'feeding the grain to the packers. t Y At the present time, Vthe grai'npassing from the elevator canvas onto the platform is fed by gravity to the packers! with the result that the grain does not always fall across theplatform in true right angularwpositiomand by reason of the greater weight of the heads of grain this `end is 4liable to get Vin advance of the butts as the grain passes to the packers, leaving the butts to drag behind, or in the case of uneven and very short grain the grain will slide forward or backward, resulting in the making up of very poor and badly shaped bundles and also in a material waste of short grain.

In accordance with the present invention, means is provided in conjunction with the platform for positively feeding the grain to the packers with the grain in true right-angular position thus insuring proper bundling of the grain and the elimination of much undesirable waste.

'I'he invention, together with its objects and advantages will be best understood from a study of the following description, taken in connection with the accompanying drawings, wherein:

Figure 1 is a fragmentary elevational view of a grain binder with parts broken away, and illustrating the application of the invention thereto.

Figure 2 is a top plan view of the platform with the invention applied thereto.

Figure 3 is a bottom plan view of the platform.

Figure 4 is a view partly in section and partly in elevation of a. roller embodying features of the present invention, and taken substantially on the line 4 4 of Figure 3.

Figure 5 is a transverse sectional view through the roller and taken on the line 5-5 of Figure 4.

Figure 6 is a longitudinal sectional view taken substantially on the line 6--6 of Figure 2.

Figure 7 is an end elevational view of a cleat hereinafter more fully referred to.

Referring more in detail to the drawings, it will be seen that 5 indicates generally the conventional laterally shiftable binder deck, the same being provided with the usual slots 6 to accommodate the lateral shiftable packers 1. One edge of the platform 5 has a sliding t within a guide channel 1 disposed at the intake end of the deck and provided at its relatively opposite ends with bearing lugs 8 in which are journalled the ends of the usual roller 9. In this conn'eof tion however, it may be stated that the roller 9 inaccordance with the present invention is a trifle smaller than what is regular equipment on binders, and further, in accordance vwith the present invention has sleeved thereon a tubular member or sleeve l0 that is shiftable longitudinally of the roller 9. l Secured to the top surface of the platform 5 in suitable position relative to the packeraccommodating-slots l `is a' plate Il of `metal or other suitable material upon which the grain fromlthe elevator` l2 of the binder falls,l and as set out in the statement of the invention, this grain, under present arrangements, feeds by gravity to the packers l.

However, in accordance With the present invention, means is provided for positively feeding the grain to the packers l and in the preferred embodiment thereof such means consists of endless conveyors l2 arranged at opposite sides of and extending in parallelism with the plate Il.

The conveyors I2 have their upper runs substantially flush with the plate ll and are in the form of endless canvas belts trained over the sleeve lll and over relatively short rollers I3 suitably supported on the platform 5 and Working in slots I4 provided therefor in the platform or deck 5.

Also, the endless aprons l2 are provided with relatively spaced transverse cleats I5 and the cleats on one conveyor are of course in alignment with the cleats on the other conveyor so as to insure the feeding of the grain with the grain, whether the grain be long or short, in true right angular position.

The sleeve I9 is retained on the roller 9 to slide longitudinally of the roller and to rotate with the roller through the medium of a rivet, pin, or the like I6, which, as shown in Figures 4 and 5, is accommodated in a longitudinal slot Il provided intermediate the ends of the roller 9.

The deck 5 is connected with the sleeve l0 so that said deck and sleeve shift simultaneously and ,as a unit through the medium of a circumferential rib IB provided on the sleeve i0 intermediate its ends, and which rib is engaged in a groove I9 provided in the offset end 20 of a cleat 2l secured as at 22 to the underside of the deck. It will thus be seen that as the platform 5 shifts laterally in either direction, sleeve I0 will shift therewith relative to the roller 9 so that drive to the conveyors l2 will be maintained.

'I'he roller 9 is of course, driven in the usual manner and through the medium of the gearing indicated generally by the reference numeral 23 and shown in Figure 1.

'It will be seen that in accordance With the present invention, the grain binder may be readily equipped with the sleeve I and the endless conveyors l2 at a very small cost and that the endless conveyors l2 will serve to bring the straws of grain evenly to the packers and binding device to the end that there will be little if any waste of grain whether the grain be uniform or uneven in length, and at the same time insuring the 'forming of well-shaped bundles.

Having thus described the invention, what is claimed as new is:

1. In a grain binder, and in combination, a roller, a laterally shiftable deck, a sleeve mounted on the roller to turn therem'th and to shift longitudinally of said roller, a pair of laterally spaced rollers mounted on said deck, endless conveyor `belts trained over said sleeve and the rollers of said' pair for feeding the straws of grain evenly to the packers of the binder, and interengaging means on the deck and said sleeve whereby said deck and sleeve Will shift laterally in' either direction.

2. In a grain binder, and in combination, a roller, and a laterally shifting deck for the binder, a sleeve mounted on said roller to turn therewith andj to shift longitudinally of said roller, a pair of laterally spaced short rollers mounted on said deck, endless conveyor belts trained over said sleeve and said short rollers for feeding the straws of grain evenly to the packers of the binder, said sleeve being provided intermediate its ends with a circumferential rib, and a cleat secured to the under side of said deck and having an offset end projecting beyond one end of the deck, said offset end of the cleat being provided with a groove receiving the rib on said sleeve whereby said sleeve will be caused to shift longitudinally of said roller incidental to a lateral shifting movement of said deck.

3. In a grain binder, and in combination, a roller and a laterally shifting deck respectively y for the binder, a sleeve mounted on said roller to turn therewith and to shift longitudinally of said roller, a pair of laterally spaced rollers mounted on said deck, endless conveyor belts trained over said sleeve and said short rollers for feeding the straws of grain evenly to the packers ofthe binder, said sleeve being provided intermediate its ends with a circumferential rib, and a cleat secured to the under side of said deck and. having an offset end projecting beyond one end of the deck, said offset end of the cleat being provided with a. groove receiving the rib on said sleeve whereby said sleeve will be caused to shift longitudinally of said roller incidental to a lateral shifting movement of said deck, and each of said conveyor belts being provided with a plurality of circumferentially spaced transversely extending cleats, the cleats on one of said belts being arranged in alignment with'the cleats on the other of said belts.
